The report analyzes how battery energy storage can provide thirteen different services across three grid levels: transmission, distribution, and behind-the-meter. It argues that while single-use batteries are often underutilized and economically unviable, 'stacking' multiple services—such as combining demand charge reduction with wholesale grid services—can make storage a cash-positive investment. Through four U.S. case studies, the report demonstrates that behind-the-meter systems are technically capable of providing the widest array of services, though significant regulatory barriers currently hinder this potential.

The report examines how rising sea levels and storm surges threaten critical electricity infrastructure, such as substations and power plants, in five major U.S. coastal regions. It finds that significant portions of the grid are already exposed to flooding, which can lead to widespread and prolonged power outages. The authors argue that current planning relies on outdated historical data and recommend a shift toward decentralized, resilient clean energy systems—including microgrids, energy storage, and combined heat and power plants—alongside infrastructure adaptation strategies like protection, accommodation, and retreat.

Large-scale solar PV systems have grown rapidly, accounting for over half of all solar capacity installed between 2010 and 2014. These projects benefit from economies of scale, with costs in 2013 averaging half of those in 2010, making them significantly cheaper than residential solar. While they generate electricity without carbon emissions or water consumption, they require substantial land area, which can impact habitats. Mitigation strategies include using degraded lands, such as landfills. Growth is supported by federal tax credits, state renewable electricity standards, and permitting reforms.

Earthjustice, representing a coalition of environmental and community groups, urges the City of Oakland to reject the development of a coal export terminal at the former Oakland Army Base. The letter asserts that the project would disproportionately burden the low-income, predominantly African American community of West Oakland with particulate matter and diesel pollution, while violating California's greenhouse gas reduction goals. It argues that proposed mitigations, such as covered rail cars, are ineffective and that the project is an economic risk due to declining global coal demand. Finally, the document claims the project lacks necessary environmental review under CEQA and NEPA and that the City possesses the legal authority to ban the terminal to protect public health.

The paper examines how different DER ownership models can be used to integrate cost-effective technologies into outdated regulatory frameworks. It argues that no single model is universal, but each can work if the value proposition aligns with the public interest and utilizes an adaptive approach prioritizing fair compensation and transparency. Utility-owned models are effective for early adoption and public goals but risk cost overruns and market power issues. Third-party and customer-owned models excel when they have transparent access to the full value of DERs through dynamic rate design or competitive markets.

The United States generates over 250 million tons of municipal solid waste and 9 trillion gallons of wastewater annually, yet recovers less than 18 percent of the potential 10.5 million metric tons of biomethane available. Current landfill systems are inefficient, leading to significant fugitive methane emissions, while many wastewater treatment facilities lack anaerobic digesters or flare excess biogas. The document advocates for a shift toward organic waste diversion and anaerobic digestion, which can result in negative lifecycle emissions. It highlights the potential for waste-derived fuel to power 10.4 million cars or 13.7 million homes and suggests that the EPA's designation of biogas-derived electricity as a renewable biofuel could generate 90 million renewable identification numbers (RINs) annually to support electric vehicle infrastructure.

The report documents a significant decline in power plant-related health impacts and emissions in the U.S. and the RGGI region between 2004 and 2012, attributing these gains to stringent emission controls, the transition from coal to natural gas, and renewable energy policies.

The report examines clean energy financing tools used by six U.S. states and Germany to scale up renewable energy and energy efficiency investments. It highlights the role of 'green banks' and other mechanisms in reducing financial risks for the private sector and overcoming barriers like high upfront costs and limited technical understanding among financiers. Case studies include Connecticut and New York's green banks, Pennsylvania and Kentucky's use of the Warehouse for Energy Efficiency Loans (WHEEL), Iowa's revolving loans, and Massachusetts's Mass Save HEAT Loan. The report concludes that these tools can help states achieve Clean Power Plan targets by leveraging limited public funds to attract significant private capital.

The report outlines a toolkit for local governments to manage the rapid expansion of unconventional oil and gas development, such as hydraulic fracturing. It details regulatory options like zoning and setbacks, non-regulatory strategies including community engagement and contractual agreements, and fiscal tools such as severance taxes and road maintenance agreements. The document emphasizes the challenge of state-level preemption and the need for local officials to act as 'honest brokers' between industry and concerned residents.

A coalition of 290 organizations and individuals opposes H.R. 1734, asserting that the bill would weaken the U.S. Environmental Protection Agency's (EPA) 2014 coal ash rule. The signatories argue the legislation would delay health protections, eliminate public access to information, and remove national standards for drinking water protection, thereby increasing risks to vulnerable communities and the environment.

Tight oil, also known as shale oil, is extracted from impermeable rock using hydraulic fracturing, a process that is more energy-intensive and polluting than conventional drilling. In the United States, tight oil's share of domestic production rose from 23 percent in 2011 to 45 percent in 2013. Key environmental concerns include flaring of associated natural gas, fugitive methane emissions, and pollution of water, air, and noise. The document argues that transitioning to cleaner transportation technologies and improving extraction infrastructure can reduce the reliance on and emissions from tight oil.

The document outlines various energy storage technologies—including pumped hydro, batteries, thermal, compressed air, flywheels, and hydrogen—detailing how they balance electricity supply and demand. It highlights the transition from a reliance on pumped hydroelectric storage toward rapidly scaling lithium-ion batteries, noting a 72 percent drop in battery capital costs between 2015 and 2019. The guide argues that energy storage enhances grid reliability, enables higher renewable energy integration, and provides community benefits by replacing polluting fossil fuel 'peaker' plants and increasing resilience against extreme weather.

The document describes the four primary components of the US electricity grid: individual generators, transmission lines, distribution networks, and consumer load. It details the technical differences between power sources, such as the low flexibility of coal and nuclear plants compared to the rapid ramping of natural gas plants. The text outlines the regulatory roles of state Public Utility Commissions (PUCs) and the federal Federal Energy Regulatory Commission (FERC), and notes the three main US transmission networks: the Western Interconnection, the Eastern Interconnection, and ERCOT. It also traces the grid's history from the victory of alternating current (AC) over direct current (DC) to the 'restructuring' of the 1970s that allowed for wholesale competition. Finally, it identifies potential improvements through energy storage, smart meters, and distributed generation like residential solar panels.

The report argues that TTIP's regulatory cooperation provisions, primarily based on EU proposals, would institutionalize oversight of US state-level legislation and regulations by federal and international bodies. This framework would likely lead to 'regulatory chill' through onerous procedural requirements, such as early warning systems and trade impact assessments, which favor industry influence over public interest. The document highlights that US states often act as the primary regulators of toxic chemicals and pesticides when federal action is lax, and that TTIP's goal of 'regulatory compatibility' could effectively set federal or international standards as a ceiling, preventing states from adopting more protective measures. It specifically warns that such mechanisms could be used to challenge state-level bans on substances like Bisphenol A (BPA) or pesticide residue monitoring programs in California.

The Measuring Up 2015 report analyzes climate action across 116 US local governments, representing approximately 14% of the US population. It finds that achieving these cities' 2050 emissions goals would be equivalent to shutting down 86 coal-fired power plants. The report highlights the success of cities like Atlanta, Cincinnati, Minneapolis, and Portland, noting that strong government leadership, supportive state policies, and private sector partnerships are critical for success. It argues that while local actions are significant, they require an enabling national policy framework, including strong power plant regulations and carbon pricing, to reach their full potential.

The report argues that current U.S. distributed solar (DPV) business models are overly customer-centric and fail to capture operational grid benefits, leading to conflict between utilities and solar companies. It proposes three 'bridge' business model building blocks: increasing access via subscription models, optimizing deployment for capacity and grid services, and bundling solar with other distributed energy resources (DERs). The authors emphasize that maximizing DPV value requires collaboration to reduce 'soft costs' and a shift toward standardized valuation methodologies and transparent data sharing between stakeholders.

A joint letter from the Attorneys General of New York, Delaware, Maryland, Massachusetts, Oregon, Rhode Island, and Vermont requests that the EPA establish methane emission standards for the distribution sector. The states argue that excluding this sector undermines the climate benefits of the Clean Power Plan and cite an EPA Inspector General's report stating that voluntary industry efforts have failed and that distribution leaks cost consumers approximately $192 million in 2011.

The document argues that Dr. Charles R. Frank Jr.'s analysis of electricity technology costs is based on outdated and methodologically flawed assumptions. Amory Lovins asserts that updating nine key variables—including capital costs and capacity factors for solar and wind power—would reverse Frank's conclusions. Lovins specifically critiques the use of national average costs, which he claims are inflated by atypical projects and do not reflect modern competitive practice.

The report details the expansion of solar energy in the U.S., focusing on rooftop photovoltaic (PV) systems, large-scale PV, and concentrating solar power (CSP). It highlights significant cost reductions, the role of state and federal incentives, and the environmental benefits of transitioning from fossil fuels to solar, while addressing grid integration challenges and land-use impacts.

A coalition of conservation organizations petitioned the New York Department of Environmental Conservation to ban second generation anticoagulant rodenticides (SGARs), arguing that these chemicals bioaccumulate in the environment and cause widespread mortality among non-target wildlife, pets, and children. The petitioners provide evidence of over 225 lethal poisoning incidents across 31 wildlife species in New York and highlight the disproportionate impact of rodenticide exposure on minority and disadvantaged communities in New York City. The petition asserts that SGARs violate state and federal wildlife protection laws, including the Migratory Bird Treaty Act, and argues that safer, effective alternatives such as first-generation anticoagulants, non-anticoagulant chemicals, and mechanical trapping are available.
